The triangle inequality applies.
In order for ACD to be a triangle, the length of AC must lie between CD-DA=0 and CD+DA=8.
In order for ABD to be a triangle, the length of AC must lie between BC-AB=3 and BC+AB=9.
The values common to both these restrictions are numbers between 3 and 8. Assuming we don't want the diagonal to be coincident with any sides, its integer length will be one of ...
{4, 5, 6, 7}
Answer:
x = 9
Step-by-step explanation:
9 to the sixth power = 531441
9 to the third power = 729
531441 = x cubed × 729
Divide by 729 on both sides.
531441 divided by 729 equals 729
729 divided by 729 equals 0
729 = x cubed
Find cube root
9x9x9 =729
Cube root of 729 is 9
x=9
Each equation equal y, right? So you can substitute 1/2x+6 for y in y=4x-1 (or 4x-1 in y=1/2x+6). Either way, you'll end up with 4x-1=1/2x+6. Then, you just solve for x.
4x-1=1/2x+6
3.5x=5
x=5/3.5
I would suggest leaving it in fraction form considering if you translate it to decimal form it will be a less precise answer.
